Okay, it sounds obvious, but it’s not always easy to tell if you’re physically hungry or not.

Emotions, your environment, and the people you’re with all play a role in whether or not you grab a snack.

But when we’re talking real hunger, you have to listen up to the physical clues: an empty, rumbling stomach or sudden sleepiness or “hanger.”

“It’s different for all of us,” says Evelyn Tribole, an intuitive eating expert in California. Other signs: feeling lightheaded, headachey, or weak.

Figuring out what true hunger feels like to you will make it easier to ID in the future. Oh, and if you’re hungry? Eat.

It’s important to know and honour your hunger cues because then you’re more likely to heed your fullness cues.

“If you respond to your hunger cues on time and with the right amount of food, you’re not living in a feast-or-famine cycle,” says Lily Nichols, owner of The Pilates Nutritionist. “This helps maintain more steady blood sugar levels. And you’re sending your body the signal that you respect and respond to its needs,” she says.

In the absence of physical signs of hunger, there’s something more going on.

Ask yourself, “What am I really feeling right now?” advises Tribole. It might be boredom or restlessness, for instance.

Then, think about what you can do to actually address that feeling. If you’re restless, getting up for a walk outside can be a healthy distraction. (It’s also been shown to quash sugar cravings when you’re stressed, per 2015 research.)

Addressing the actual need will fulfill you in a way that food likely can’t.

Sometimes you may use food to procrastinate on a task or because you’re not willing to give yourself a break otherwise, says Tribole. Give yourself permission to take a breather every now and again so you don’t have to use food as an excuse.

If you’re having trouble starting on a task, set a timer for 10, 15, or 20 minutes and promise yourself you’ll work that long. After the time is up, you can have the snack if you still want to.

So you had an epic night of eating and boozing. Today, oddly, you’re hungry for all the vegetables.

This means your body is working and self-correcting, says Tribole. It’s huge progress and a great sign that you’re able to apply some principles of intuitive eating (eat what your body craves in an amount that satisfies).

It can be a big relief to trust that your body knows what it wants - as long as you listen.
